5 trapped crew of a submarinel when the latter is disabled. I

An objectof the'invention is to provide a safety apparatusofthis type which inclu-des a marking buoy and communication buoy, the release of Awhich is controlled from'the interior of the vessel. 'After this buoy has floated to the surface, it may be picked up by a resycue ship, and the .cable which is attached to the buoy drawn upwardly to extend a normally collapsed hose to the surface. After this hose has been fully extended and its sealing cap removed at the surface of the water, the crew of the submarine may beV removed through the-hose.

f Objects of the invention are to provide an apparatus of this character which may be conveniently attached 'to any conv'entional 'type of submersible'vessel, and whichl may be conveniently manipulated from the interior of the vessel to release the markingbuoy.

With the 'above notedpand other objects in view, the invention consists in certain novel features -of construction and"` combinations yand arrangements of parts yas vwill bemore lfully set forth and pointedvout inthe claims.

Thelinvention may be more fully understood from the following description in connection with the accompanying drawings, wherein- Fig. 1 is a somewhat. diagrammatic view showing a submarine resting on the bottom of the sea, andthe released marking-buoy floating on the surface. j

Fig. 2 is a similar. view, but showing the marking buoy picked up by a 'derrick, and the hose or tube fully extended preparatory to re- Vmovingthehose cap' and withdrawingthe f crew of the vessel through the hose. Y Y t Fig. 3 isanenlarged longitudinalsectional view. throughjthe hoseereceiving shell and the hose-protecting sheathing, vthe t hose being shown kin elevation.

Fig. 7 is a top plan view of Fig. 6.

Fig. 8 is an enlarged vertical sectional view through a section of the extended hose.

Fig. 9 is an enlarged transverse sectional view on the line 9-9 of Fig. 4. n

Fig. 10 is a transverse sectional view on the line 10-10 of Fig. 8. l y Y In the drawings I have used the reference numeral 10 to designate a submarine having lanopening 12 in its deck within which is accommodated a vertical metal cylinder 13, the upperr end of which projects above the of lhose .deck of the ship, and the lower end of which projectsinto the interior of the ship. The top of the cylinder 13 is normally sealed by a cover 14v swivelly connected at 15 to a flange 16 onthe cylinder. A verticallydisposed operating shaft 17-for the cover 14 extends downwardly through bearings 18 and terminates within the submarine; the lower end of this shaft carrying a Apair o-f crank handles 19. As thehandles 19'are rotated to swing the cover 14 about its ypivot 15, the' cover .moves on to a lsupporting framework 2O so that it will not be snapped off by the water pressure. Framework 2O is preferably braced as at 21. by bracing members which are connected tothe cylinder 10.

s .In orderto break the seal at thecover 14, which otherwise mightmake it difficult to manipulate the handles 19, the cover is prof vided witha projecting lug 21 received with- 1n a notch 22 in theupper end of a shaft 23 preferably disposed on the opposite side ofthe cylinder from the shaft 17, and mounted in bearings 24. Shaft 23 has a threaded `connection at 25 with a bushing-26 secured i to thelunder face of the submarine deck, and .byturning the'handle 27 atthe lowerend ofjthe shaft 23, this shaft may be raised,.forc ring thefree edge of the cover 14 slightly upwardly and breaking the seal, so that the cover may be `conveniently swung to the :dotted line position of Fig. 7 by the handles l The lower end of the cylinder 14 is closed spaced series of stiliening rings; certain;

by a hinged cover '28, the free edge of whichv is releasably held by any suitable clamping means 29 manipulable from the interior of the ship. f

Housed Within the cylinder 10 is a collaps ible hose 30 off fairly. large diame'ter.l The lower 'endof this' hose is connected to a collar 3l fixed to the bottom of the ycylinderfl'()` and the upperend ofthe hose is-:closedby ay sealing cap 32. The hose is braced by a of which may, if desired, carry spiders 34: on

which are mounted protective yshellsf'. As

the hose )is collapsed,` the shells 35. nest or telescope one? Within theV other as` seenA in Fig. 6, and as the hose is extended, the nested shells 35 vare `drawn-out as-'illustrated in Arrangedjwithin the; cylinder above thecollapsedy hose j30 is a marking buoy '36 lattached to a-'cable 37 Which. may. carrylight Wires; telephone Wi`res,'air`lines, etc.- The cable preferably coiledupon the top ofthe' hosel cap 32;asseen in Fig'. 6".

.The upper portionl of: the hose? 3()l which not protected by' theteleseopingf shells'V 35 may be vreinforced if desired by'a" staggered 'arrangement Aor",4 rods 40, each rod being mountedi upon' one ringfof the hose and Work@ Y ing through'gan eye Llly o'nan adiacentring.

B'y staggeringf'the rods'they do not'interlfere vwith each otherV asjthe hose' is collapsed'. kThe operation' of the device' is substantial'- ly as follows. Y With the-submarine disabled l andr'esting-on the bottom', as' shownI in Fig.

4for instance as the' Vloatin'gderri'ck iO-reaches thescene', they may pick'upthe-'marking buoy BG and communicate with th'e'creyy7 of thejves- :sel by telephoneV wires' etc., which are` carried by thebuoy; p `(Dbviou'sly also, the buoy may carrymeans for providingthe" subm'a VV rine' with light,jpower`and fresh air. Such means econsistin'g of 'power l cables7 yair lines,

etna` arranged2 Withingthe'main cable 37( Having picked( u'pthe markingv buoy 36,

Obviously, the'combination 'of the still"Y rings V33 tyitli the prot'ective shells 35l will serve toA prevent eolla'psecf y oi the rings.

the hose or injury tothe hose by engagement with extraneous objects. Inasmuch as the Water pressure vnear the surface is Vmuch less :than near the bottom, the simpler and lighter varrangement of reinforcing rods 40 mayl reiplace theshellslat thispoint.

AVarious changes andjalterations might be` made in" thegenera'l-/orm andarrange-v ments-o the parts described Without departing-from the innentiom. Hence I do not Wish to limit myself' to the'adetailsset forth, but shallconsi'derfmyself at liberty to make such changes land alterationsas 'fairly fall Within the-spirit andsc'opefof the appended claims.
